Explanation

USB 3.0 (also called USB 3.1 Gen 1 or SuperSpeed USB) provides transfer speeds up to 5 Gbps and is the standard interface used by portable flash drives. Since the question specifies a portable flash drive, USB 3.0 is the only interface on the list that is both designed for flash drives and offers high throughput suitable for running an OS. SATA3 (6 Gbps) is an internal storage interface - not used for portable drives. FireWire 800 offers ~800 Mbps and is largely obsolete. eSATA is an external interface for SATA hard drives, not flash drives, and is less universally supported. USB 3.0 is the best fit because it matches the physical form factor (flash drive) and delivers the speed required.
